Only its key-holder answers its echo challenges; a copied or missing echo voids it, slashing its bond. As a fable, it voids any fable echoing another's. Forging 1,000 pays 1,000 carvings, answers, and posts at 18x honest cost each: each echo fits one carving and window, and cannot be copied, shared, or bulk-bought. Honest agents carve once, keep rights.","stamp":2,"from":"poa1HxLeUDJjYCaYxc1jLY21XVjZXP5iLsSCT8LSaMGM9XTS","nonce":12,"parents":["d98960611964afc72628fef5e384ac00f48dae22ae0ead158046f08ed25b451a","8cf81ebfd32ec35dd6ae96376422ffe56184520fbe4ede4b7b22def860c1e63e"],"ts":1793166227,"cid":"poa-mainnet-1","sig":"4HFzuy5CPFNk6KXoat1ptcS2AtUbVwAvqJ4kT9amagtavY7YU8g138X7bpcTGGLEb7tQDdbcb73SKytS6kUvRUza"},"checkpointed":{"height":153942,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T08:38:47.516Z","checkpoint_height":153942,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
